In the past in order to make good home movies one needed either a Mac or a Windows PC. There were no good video editors for Linux in the past. Today with Jahshaka and Main Actor the things that could only be done on a Mac or a Wintel machine can now be done on a Lintel machine as well.

The statement that both programs aren't GNOME-like does actually make sense. SuSE is quite a KDE-distribution, so it is nice when the movie-editor uses the same toolkit as KDE does. And of course it is nice for a home user that when he buys SuSE, he gets MainActor for free, and that his camcorder is auto-detected and "just works".
Now what I feel missing is a more detailed review about Jahshaka and MainActor. How do they look like? Are there things you feel are missing? Is it crashy (MainActor on SuSE 7.3 was _very_ unstable and not even the full version!)? How fast are they compared to Windows? And so on.
